Abstract:
Der sechste Lagebericht des zwischenstaatlichen Ausschusses für Klimaänderungen (IPCC, Intergovernmental Panel on Climate Change) aus dem Jahr 2021 hat die Welt in hohem Maße sensibilisiert. Die IPCC-Prognosen besagen, dass die globale Temperatur um bis zu 5 Grad Celsius steigen könnte (vgl. IPCC 2021:13). Dies ist ein Extremszenario und daher unwahrscheinlich, aber eben auch nicht ausgeschlossen. 
 An dieser Situation ist die kommerzielle Schifffahrt maßgeblich beteiligt. Laut der 4. IMO Greenhouse Gas Study haben Schiffe mit einer Bruttoraumzahl über 100 weltweit im Jahr 2018 rund 1.076

Abstract:
Reactions of 5-methylphenanthridinium iodide (I) with oxygen, nitrogen, and carbon nucleophiles, respectively, were studied. 5-Methylphenanthridinium iodide (I) yielded in the basic aqueous medium 5-methyl-6-phenanthridone (II) and 5,6-dihydro-5-methylphenanthridine (III). By NMR spectroscopy in the D2O-CD3CN solution 5,6-dihydro-6-deuteroxy-5-methylphenanthridine (IVb) (pseudobase) was observed as an immediate unstable product. 5-Methylphenanthridinium iodide (I) gave the corresponding adducts with methoxide and ethoxide anions, morpholine, piperidine, pyrrolidine, cyanide anion and acetone.

Abstract Internal corrosion occurs in natural gas pipelines primarily due to the presence of water, carbon dioxide, and hydrogen sulfide. Internal corrosion can eventually result in leakage, cracks, and rupture of the pipeline.

The corrosion behavior of carbon steel coated with self-healing ZnCr and ZnNb cold spray coatings was investigated in a natural gas environment.

The results indicate that crystalline FeCO3 forms in the presence of solely water and CO2. However, the combined introduction of small concentrations of O2 and SO2 (as low as 20 and 2 ppm (mole), respectively) change FeCO3 crystal morphology.

AC impedance was used to measure and correct for solution resistance while weight loss was used to verify the corrosion rate magnitude.
